The MC74HC540A is identical in pinout to the LS540. The device inputs are compatible with Standard CMOS outputs. External pullup resistors make them compatible with LSTTL outputs.
The HC540A is an octal inverting buffer/line driver/line receiver designed to be used with 3state memory address drivers, clock drivers, and other busoriented systems. This device features inputs and outputs on opposite sides of the package and two ANDed activelow output enables.
The HC540A is similar in function to the HC541A, which has noninverting outputs.
